Editing Usability testing (section)

===Expert review===

Expert review is another general method of usability testing. As the name suggests, this method relies on bringing in experts with experience in the field (possibly from companies that specialize in usability testing) to evaluate the usability of a product.

A [[heuristic evaluation]] or '''usability audit''' is an evaluation of an interface by one or more human factors experts. Evaluators measure the usability, efficiency, and effectiveness of the interface based on usability principles, such as the 10 usability heuristics originally defined by [[Jakob Nielsen (usability consultant)|Jakob Nielsen]] in 1994.<ref>{{cite web|title=Heuristic Evaluation|url=http://www.usabilityfirst.com/usability-methods/heuristic-evaluation/|publisher=Usability First|access-date=April 9, 2013}}</ref>

Nielsen's usability heuristics, which have continued to evolve in response to user research and new devices, include:
* Visibility of system status
* Match between system and the real world
* User control and freedom
* Consistency and standards
* Error prevention
* Recognition rather than recall
* Flexibility and efficiency of use
* Aesthetic and minimalist design
* Help users recognize, diagnose, and recover from errors
* Help and documentation
